7ca1d488 | 41 | The RTC device that will be used to (re)initialize the system |
ae64d169 AZ |
42 | clock, usually rtc0. Initialization is done when the system |
43 | starts up, and when it resumes from a low power state. This | |
779d2089 DB |
44 | device should record time in UTC, since the kernel won't do |
45 | timezone correction. | |
7ca1d488 | 46 | |
55ff1aba DB |
47 | The driver for this RTC device must be loaded before late_initcall |
48 | functions run, so it must usually be statically linked. | |
49 | ||
7ca1d488 | 50 | This clock should be battery-backed, so that it reads the correct |
ae64d169 | 51 | time when the system boots from a power-off state. Otherwise, your |
7ca1d488 DB |
52 | system will need an external clock source (like an NTP server). |
53 | ||
54 | If the clock you specify here is not battery backed, it may still | |
55 | be useful to reinitialize system time when resuming from system | |
09b6bdb3 | 56 | sleep states. Do not specify an RTC here unless it stays powered |
7ca1d488 | 57 | during all this system's supported sleep states. |
